Juan,

What kind of ignition problems are you experiencing?

Quite a bit of the rhetoric on the Permatune site is BS.

The pickup coil in your distributor is very fine copper wire, and the resistance will rise with temperature, but probably not as much as you measured. However ... I am certain that the test values Porsche uses are for moderate temperatures not to exceed 100°F, not elevated to 200°F++. So, I believe your pickup coil is within specs!

I suspect there is some corrosion present on the connector at the distributor cable junction to the engine harness, and also at the 6-pin connector at the CDI-unit. you can clean them with household vinegar -- alow to sit 2-5 minutes, then rinse with distilled water, and finally ... rinse again with 90% isopropyl alcohol. The sides of the female 1/4" Faston connectors can be crimped LIGHTLY with needle-nose pliers ... but, be SURE that there is still a gap present! After testing is complete, apply silicone grease such as Dow Corning 111, 112, or 4 to the comnnectors to prevent corrosion in the future.

If further problems persist, there is a $30 replacement green coaxial cable assembly to replace the cable that comes out of the distributor and makes a sharp bend to join the engine wiring harness. Problems with that cable are known to cause an intermittent miss or complete cutouts and loss of power. Good luck!
